Energy storage system is an important part which regulates power performance and ensure the quality of load power supply. The constant current control of energy storage converter is utilized for the safety and lifetime of the battery pack. it is difficult for the linear PI control to adapt to the nonlinear and dynamic change characteristics of battery system and maintain the stable performance. This paper employed the fuzzy control algorithm and modified the control strategy to an adaptive manner according to the error and the rate of change of error. The experimental results show that fuzzy logic controller possesses better performance than PI controller.
